> why would a business run the same without the person who did all the work doing it? This is 100% a concern. If a business is successful because the founder puts in insane amount of work that makes it less valuable to buy. You ask the question: What would happen if the founders take a multi-month vacation? If the business would keep pumping money, either because it is passive, or because they trained people well and the machine is working without them, then that is a good candidate to buy. If it would fall, or cease to be a business that is a bad business to buy.
